[root@gw squid]# wbinfo -t

[root@gw squid]# wbinfo -p

all work's but when i put :

[root@gw squid]# ./wb_group -d
/wb_group[28942](wb_check_group.c:344): External ACL winbindd group

/wb_group[28942](wb_check_group.c:308): Can't contact winbindd. Dying

[root@gw squid]# ./wb_auth -d
/wb_auth[28952](wb_basic_auth.c:183): basic winbindd auth helper build
